USGS Contact Information

The USGS provides practical, unbiased information about the Nation's rivers and streams that is
crucial in mitigating hazards associated with floods. This site provides information about the
USGS activities, data, and services provided during regional high-flow events, such as
hurricanes or multi-state flooding events. The USGS response to these events is typically
managed by the National Floods Specialist.

The USGS Flood Inundation Mapping Program (FIM) partners with local communities and other
government agencies to develop and validate flood inundation map libraries. Click the title above to visit the
USGS FIM website and learn more about
available tools. Completed projects are collected on the USGS National Flood Inundation Mapper, brought to you by
the USGS Wisconsin Internet Mapping Group (WiM). Click the image on the left to go straight to the
Mapper.

The USGS StreamStats website is a GIS-based web tool for estimating streamflows at gaged
and ungaged locations. Features similar to the NSS program are presented to users with no
programs to install. Users can visit the StreamStats website linked here and click on a
stream location on the interactive map to compute estimated streamflows for floods and
other statistics. Additional statistics at gaged locations are also presented.

Select your favorite USGS streamgage from the USGS WaterAlert map, then set water stage or
streamflow thresholds to receive instant notifications sent to your email address or mobile
device. Click the image at left or the title above to go to the map and select your site(s).

Want to know what's happening right now? Request real-time information from any USGS
streamgage with the USGS WaterNow text service. This service responds to your text message
with information about the current stage, streamflow, or other parameters collected at the
gage. Click the image at left or the title above to learn how.

The USGS Streamer is a super-friendly interactive map that helps you explore America's
larger streams by tracing upstream to their sources or downstream to where they empty.
The map includes layers for weather radar and near-real-time streamflow conditions.

Dr. Robert Holmes discusses causes and effects of flooding, including a look at aspects of
the 2011 epic flooding, and how USGS science assists in the overall flood mitigation efforts
of the United States.

The USGS Natural Hazards Mission Area has been given responsibility for overseeing the bureau's
emergency management activities. This function includes the USGS Hazard Response Executive
Committee, which provides executive direction, oversight, and support to USGS managers in
responding to major hazard events. During incidents of national significance, the USGS provides
support to certain National Response Framework emergency support functions.

The USGS operates an event-based mobile storm-surge sensor network to capture information about coastal
and inland storm tides. Click the title above to learn more about the

The National Water Information System (NWIS) is the USGS water data portal where you can
find a wealth of historic and real-time data related to floods. Click the image at left or
the title above to go to the NWIS website where you can query for peak streamflow data by
station, State, or region. Or, click here
to go to the main NWIS page for a broader range of data.

USGS researchers across the nation have developed equations for estimating flood streamflows
as well as other statistics at ungaged sites. These equations are collected for easy
access and computation through the downloadable NSS program and the associated
NSS/StreamStats database. Users can download the NSS program and database from the NSS
website linked here. Users will also find reports detailing the development and proper use
of every equation in the NSS/StreamStats database.

The USGS SWSTAT program contains a number of options for statistically analyzing time-series
data. Output options include minimum, maximum, mean, and standard deviation of a
time-series, as well as flow-duration analyses, log-Pearson Type III frequency analyses,
trends, and others using standard textbook procedures. Click the title above or the image
